My invention will be more fully set forth in the following descriptiontaken'in connec the corresponding tion with the accompanyingdrawings andthe invention Will be more particularly delined inthe appended claims.

In the drawings, Figure 1 is a central vertical transverse section of amachine of the general construction and arrangement of parts set forthin `my patent, rovided with my present im rovements. ig. 2, is aerspective view o a fragmentary rtion o the new roll. Fig. 3 shows thero in front elevation, the shaft being broken away. Fig. 4 illustratesin top. lan the eect of my improvement in app ying cement to 'an innersoe. l

The general features of construction and operation of my machine will beunderstood by'reference to my before mentioned patent,

arts being similarly lettered herein arid t erefore not furtherdescribed. l e

The roll a3 which is preferably of highly resilient material asdescribed in said atent is supplied with cement a2 by a distri utingroll a and the `inner-sole is fe thereto .by the superimposed feed rolla, a projecting abut, ment or stop a being provide against which thefront end of the innensole may be placed in order to bring it exactly inposition.

In accordance with this invention the re- My `invention/is anlmprovement in ma-V i cement as desired.

In the, illustrated' 'embodiment 0f. the invention the .resilientPreferably this I that the above character and results may be obtainedto best advantage by having a knit--l ted,brous 'and absorbent Jacketprepared as shown in' Figs. 2 andv 3, this jacket or covering beingvmade of strong cord or thread, coarsely knittedso as to give it therequired depth `or thickness, strength, permanence,`

and binding structure.

v 'The covering is made in open-Work fashion and preferably it has adelinite arrangement of openings or ockets c', c2 arraned 1n similarlongitudina series, saidseries v`being alternating or sta gered withrelation4 to each other so that t e openings or pockets c come out ofcircumferential alinement with the openings or pockets c2. The result ofthis construction 1s that, in use, the cement is deposited regularly indaubs, as it were, as indicated at c, Fig. 4, although theentire'surface c4 receives some cement,

Preferably the open- Work jacket is mounted on a flexible baseorretainer of thin yieidingl, coarse-mesh, or non-rforaminous. materiasuch as burlap, netting, etc., as indicated at d, which, if desired, maybe secured to the jacket at intervals, as indicated at 05, this baseserving as a PIOtCtOI' fOrv retaining and preserving the resilientmaterial 'of the roll Without' interfering with its freeyieldingeiiciency.

The combination of the resilient substance of the roll itself With' thereadily iieXing covering or outer surface described, gives uniformityof. action and long life to the roll,

If th'e peri heral pocketed surface of the roll is formed b a jacketsuch as that described above, t e jacket will preferably be -removableso that 1f it, or the retainer c in case the retainer is used, becomesWorn or injured they may be replaced bynew coverm upon the sameresilient ro l body.

urther advantages, and other equivalent embodiments, of my inventionwill occur to those skilled in the art, in view of the foregoingexplanation thereof and as already intimated, I do' not intend torestrict myself in all respects to the details herein presented, asvarious changes in material and construction may be resorted to withoutdeparting from the s irit and scope of my invention. I wis it understoodlthat while m machine is particularly adapted to inner-so es, it maytaps and the e, and that accordingly I use the wordl inner-sole in theclaims and elsewhere, without intending to restrict the machine in anyway thereto.

Having described my invention, what I claim as new and desire to secureby Letters Patent, isz- 1. In a machine of the kind described, acement-applying roll having a resilient body 45 portion provided on itsoutside with a perijlheral surface of durable, fiexible material fu ofholes. Y
